    摘要： A method and composition are shown for producing a positive-acting photoimagible epoxy resin. In addition to the epoxy resin, the compositions include a dual component cross-linking system which combines a basic curing agent with an onium or arylonium salt. The onium or arylonium salt produces a protic acid upon exposure to irradiation causing a reaction with the basic curing agent which renders the agent ineffective as an epoxy curing agent during subsequent heating. During a subsequent bake operation, only the unexposed regions of the epoxy will cross-link. As a result, the exposed areas wash away, leaving only the cured reverse image.

    摘要： According to the present invention, good image resolution of a cationically polymerized epoxy based coating, such as a solder mask or dielectric or etch resist, is provided by combining a cationically polymerized epoxy based coating with conventional epoxy glass substrates cured with a curing agent that does not produce basic reaction products. Preferably, the coating is photoimagable. The method for making the same is also provided. The coating material includes an epoxy resin system comprising between from about 10% to about 90%, preferably about 28% to about 57% by weight of a polyol epoxy resin, and from about 10% to about 90%, preferably about 43% to 72% by weight, of a brominated epoxy resin. Optionally, a polyepoxy resin or an epoxy creosol novolak resin is added to the resin system. The polyepoxy resin may be added from an effective amount up to less than 90% of the resin system; the epoxy creosol novolak may be added from an effective amount up to about 80 pph.
